Question

Write Trick to Learn Trignometric Ratios??

Answer 1

Remembering values of standard angles can be difficult. But with the method shown below you can easily remember the values of standard angles.

First of all write down the values of standard angles.



 

Then write numbers from 0 to 4 below them as shown below.



 

Then divide all of them by 4.



 

Take square root of all of them.



 

Then write resultant value.



 

Then write those value in reverse order below them.



 

Then divide values of first line with second line and write resultant values as third line.



 

Then write sin, cos and tan on the left hand side as shown below.



 

So, by this way you can easily remember values of standard angles.

Values of Cosec, Sec and Cot can be found by taking inverse of Sin, cos and tan respectively for the given angle.

 

Answer 2

Heya

HERE IS YOUR ANSWER!!!

-------------------------------------------------

It's quite easy to learn trigonometric ratios. You just have to learn the ratios of sin, then you can automatically find all others.

To learn the ratios of sin just write the numbers from 0-4 , divide them by four and do their underroot. In this way you can learn the values for sin.

Cos is just reverse of sin, you have to put the values from 4-0 this time and follow the same rules.

Divide sin by cos to find tan.

Do reciprocal of sin to find cosec.

Do reciprocal of cos to find sec.

Do reciprocal of tan to find cot.
